I applied online. The process took 2 weeks. I interviewed at Arista Networks (Vancouver, BC) in Feb 2020
Interview
1 hour onsite interview for the first round. All questions are technical questions. Start with debugging and then ask to write some simple code using vim on mac.
Pretty good, not too complicated, was comfortable. Mostly LC questions, and was easy enough that you should be able to do it after doing NC150. good luck for the interview!
Starts with online test, then three rounds of technical interviews follow.
Not a lot of discussion, just go straight to the technical challenges which have to be solved in time
I interviewed at Arista Networks (Warsaw, Masovia)
Interview
By now I have had only first interview, that was focused on pure DSA. Despite that I would already recommend checking out gdb, cause it came in handy in my case.
